A restless and restless sleep promotes stress and increases conflict in the couple.

A lack of sleep increases stress in the couple and does not help resolve conflicts, according to the results of a study published in the medical journal.

Researchers at the Ohio State University Institute for Behavioral Medicine Research in the United States conducted a study with 43 couples. Whenever the couples met the scientists, they provided blood samples and reported how many hours they had slept the previous two nights. Then, the researchers asked the couples to solve a subject that causes a conflict in their marriage. Blood samples were collected again following the discussion.
